THE ACOUSTICAL SOCIETY OF AMERICA STANDARDS PROGRAM
Paul D. Schomer, Chair ASACOS&
Susan Blaeser, Standards ManagerUpdated Nov. 2007
#2
Why Standardize?
Some reasons are obvious -• Safety• Assure interoperability of parts• Benefit from “best in class” information• Strive for qualitySome are less tangible - • Provide basis for government regulation• Promote product acceptance• Facilitate entry into new markets• Level the competitive field
#3
Constituent Organizations of the ASA Standards Secretariat
#4
ASACOSAcoustical Society of America Committee on Standards
• ASACOS – Policy, finances and program oversight– Representative of each ASA Technical Committee – Chairs & Vice Chairs of Standards Committees – Ex Officio representatives from ASA, TAGs, etc.– Acts on behalf of ASA and makes recommendations to the Executive
Council• Executive Committee – Acts for ASACOS when quick action is needed
– Chair, Vice-Chair & Standards Manager • Steering Committee – Procedural matters– Executive Committee Members– Chairs of Committees
#5
Accredited Standards Committees OperatingUnder ANSI Procedures
• S1- Acoustics• S2- Mechanical
Vibration and Shock• S3- Bioacoustics – S3/SC 1 Animal
Bioacoustics• S12- Noise
#6
S1, Acoustics
• Acoustical terminology• Sound level meters• Microphones• Acoustical calibrators• Filters• Physical sound measurements• Noise dosimeters• Surface impedance
measurement
#7
S2, Mechanical Vibration and Shock
• Calibration of shock and vibration transducers
• Characteristics of resilient mounting
• Mechanical vibration of rotating machines
• Human exposure to vibration
• Balancing
#8
S3, Bioacoustics
• Hearing aid specifications• Audiometry• Speech interference levels• Articulation index• Threshold of hearing--
Audiometric Zero• Calculation of loudness
levels
#9
S3/SC 1, Animal Bioacoustics
• Effects of sound on animals (aquatic and terrestrial)
• Instrumentation• Weighting• Terminology
NEW
#10
S12, Noise
• Environmental noise measurement and assessment
• Sound power measurement
• Hearing conservation• Factory noise
measurement• Noise from ships
• Liaison Groups (e.g., SAE, ASTM)– motor vehicles, aircraft, construction
equipment, power tools
#11
ISO/IEC Technical Advisory Groups (TAGs)Operating Under ANSI Accredited Procedures• IEC/TC29
Electroacoustics
• ISO/TC 43 Acoustics• ISO/TC 43/SC 1 Noise
Continued on next slide.
#12
ISO/IEC Technical Advisory Groups (TAGs)Operating Under ANSI Accredited Procedures (con’t.)
• ISO/TC 108 Mechanical vibration, shock and condition monitoring – SC 2 Measurement and evaluation of mechanical vibration
and shock as applied to machines, vehicles and structures– SC 3 Use and calibration of vibration and shock measuring
instruments– SC 4 Human exposure to mechanical vibration
and shock– SC 5 Condition monitoring and
diagnostics of machines– SC 6 Vibration and shock generating
systems
#13
U.S. Technical Advisory Groups
– Organizational members– Chair (vice chair or co-chair) – Provides pool of experts who may participate in
ISO/IEC working groups– Establishes U.S. position on ISO/IEC matters more
than 80 times per year For each ISO/IEC ballot a “coordinator” is
appointed Comments solicited from TAG members Coordinated comments and vote submitted
through ANSI (USNC in IEC)
#14
ISO Secretariats Administered by ASA
• ISO/TC 108 Mechanical vibration, shock and condition monitoring
• ISO/TC 108/SC 5 Condition monitoring and diagnostics of machines
#15
Primary Documents
• ANSI Approved Documents– American National
Standards– Nationally Adopted
International Standards– Other, e.g., Technical
Reports• ISO/IEC Approved Documents– ISO/IEC Standards– Other, e.g., Technical
Reports, Technical Specifications
#16
Standards Committee & Subcommittee Membership
Voting• Organizational Members
Companies Societies, Trade Assoc. Government agencies
Non-voting Individual Experts Working Group Chairs• Working Group Members
Ad hoc Groups Advisory Groups Liaison Groups, e.g., SAE, ASTM
#17
ANSI Standards Development Process
• New Work Effort– Proposal– Ballot Approval– Allocate to existing or new WG
• Working Group– Develop Draft Document– Ballot by S-Committee– Try to Reverse Negative Votes or Positions
Adopt 30-day review Re-ballot a substantially new document
– Public review and comment• Develop Consensus--Much more than a plurality ~90 %• 5-year Review and Reaffirmation
#18
ISO Standards Development Process
• New Work Effort– Proposal– Ballot Approval-- TAG Vote – Allocate to existing or new WG
• Working Group– Working Draft– Develop Committee Draft (CD-1, CD-2, etc.)
Ballot by member bodies to become a Draft International Standard (DIS)--TAG Vote
• Committee– Ballot DIS to become Final DIS-- TAG Vote – Ballot FDIS to become a Standard-- TAG Vote
67% of P-members voting; 75 % of votes• 5-year Review and Reaffirmation
#19
Summary
• National Standard (ANSI)– Ballot to the S-Committee (or Subcommittee) Members
• International Standard (ISO/IEC)– Ballot to the TAG (determines U.S. position)
TAG Members Liaison Groups USA Representative USA Document Coordinator TAG Chair
#20
Result
• Impact of National and International Standards– Health and safety – e.g. Speech Interference– Public good – e.g. Classroom Acoustics – Measurement – e.g. Sound Power– Instruments – e.g., Sound Level Meter– Trade
